Claude Opus 5.5 Lands on AWS with Better Token Efficiency

AWS now offers Claude Opus 5.5, Anthropic's most capable Opus model, which handles long-running coding and knowledge work while using fewer tokens at lower costs than its predecessor. You can access it through Amazon Bedrock (with zero data retention and regional residency) or Claude Platform on AWS, both integrated with AWS infrastructure and billing.
